The solution-mediated syntheses and single crystal structures of (N2C6H14)·Zn(HPO4)2·H2O (I), H3N(CH2)3NH3·Zn2(HPO4)3 (II), and (N2C6H14)·Zn3(HPO4)4 (III) are described. These phases contain vertex-sharing Zn04 and HP04 tetrahedra, accompanied by doubly- protonated organic cations. Despite their formal chemical relationship, as members of the series of t·Znn(HP04)n+1 (t= template, n = 1-3), these phases adopt fimdamentally different crystal structures, as one-dimensional, two-dimensional, and three-dimensional Zn04/HP04 networks, for I, II, and III respectively. Similarities and differences to some other zinc phosphates are briefly discussed. Crystal data: (N2C6H14)·Zn(HP04)2·H20, Mr = 389.54, monoclinic, space group P21/n (No. 14), a = 9.864 (4) Å, b = 8.679 (4) Å, c = 15.780 (3) Å, β = 106.86 (2)°, V= 1294.2 (8) Å3, Z = 4, R(F) = 4.58%, RW(F) = 5.28% [1055 reflections with I >3σ(I)]. H3N(CH2)3NH3·Zn2(HP04)3, Mr = 494.84, monoclinic, space group P21/c (No. 14), a= 8.593 (2)Å, b= 9.602 (2)Å, c= 17.001 (3)Å, β= 93.571 (8)°, V = 1400.0 (5) Å3, Z = 4, R(F) = 4.09%, RW(F) = 4.81% [2794 reflections with I > 3σ (I)]. (N2C6H14)·Zn3(HP04)4, Mr= 694.25, monoclinic, space group P21/n (No. 14), a = 9.535 (2) Å, b = 23.246 (4)Å, c= 9.587 (2)Å, β= 117.74 (2)°, V= 1880.8 (8) Å3, Z = 4, R(F) = 3.23%, RW(F) = 3.89% [4255 reflections with 1> 3σ(I)].
